Abstract
The invention provides a guiding support device and a road-rail tractor. The guiding support device comprises a guide pulley assembly and a support cylinder, wherein the guide pulley assembly comprises a wheel axle and guide pulleys arranged at the two ends of the wheel axle; the guiding support device also comprises a linkage mechanism, the two ends of the linkage mechanism are respectively hinged with the guide pulleys arranged at the two ends of the wheel axle, and the linkage mechanism is used for transmitting a force parallel to the direction of the wheel axle, so that the guide pulleys arranged at the two ends of the wheel axle make a turn in a same direction. After the linkage mechanism is arranged, the guide pulleys arranged at the two ends of the wheel axle do not move in an inwards-splayed or outwards-splayed motion form, and just can move in a parallel motion form, in such a way, the running resistance of a vehicle in the process of running is greatly reduced, and the occurrence probability of a derailment phenomenon is reduced, thereby improving the driving safety.
Description
Technical field
The present invention relates to the track traffic technology, relate in particular to a kind of guiding support device and road and rail double duty tractor.
Background technology
The road and rail double duty tractor is meant and can walks in orbit, again can be at the tractor truck of highway up train, and it is the power assisted vehicle of railway transportation.The road and rail double duty tractor mainly is applicable to small-sized shunting service and highway and other special-purpose the trailer operation on the ground in the Railways Stations section; The towage that also is applicable to harbour, harbour and industrial and mining enterprises is used.
The most frequently used combined car is that rubber tire drives at present, and when vehicle was walked on highway, rubber tire was enough to satisfy the demands.But when vehicle was walked on rail, because rail is narrower and certain gradient is arranged, rubber wheel did not have guide function, can't on rail, walk separately, so track adjusting wheel need be set, moved along rail with the guiding rubber wheel.Track adjusting wheel is to be installed on the combined car through guiding support device.The effect of guiding support device is to lift or put down track adjusting wheel, and when the road and rail double duty tractor moved on rail, guiding support device put down track adjusting wheel, and track adjusting wheel plays directional tagging along the rail operation; When the road and rail double duty tractor moved on highway, guiding support device lifted track adjusting wheel, and track adjusting wheel is inoperative.
Guiding support device comprises track adjusting wheel composition and support cylinder.Track adjusting wheel is formed the track adjusting wheel that comprises wheel shaft and be arranged on said wheel shaft two ends.The cylinder body of support cylinder is used for captiveing joint with car body, and piston rod is captiveed joint with the right wheel shaft of track adjusting wheel.The quantity of support cylinder is two, is symmetricly set on the two ends of wheel shaft.The piston rod of support cylinder stretches out, and track adjusting wheel contacts with rail; Otherwise then do not contact.
In the practical application, at Ackermann steer angle, the track adjusting wheel that is positioned at the wheel shaft two ends is difficult to synchronous turning, makes vehicle when operation, be easy to occur derailment occurring, and the safety of vehicle operating is low.
Summary of the invention
The present invention provides a kind of guiding support device and road and rail double duty tractor, is used to optimize the structure of guiding support device, reduces the derailment occurring in the vehicle operating.
The invention provides a kind of guiding support device, comprise track adjusting wheel composition and support cylinder, said track adjusting wheel is formed the track adjusting wheel that comprises wheel shaft and be arranged on said wheel shaft two ends, wherein, also comprises:
Link gear, the two ends of said link gear are hinged with the track adjusting wheel at said wheel shaft two ends respectively, are used for transmitting being parallel to saidly taking turns axial power, so that be positioned at the equidirectional turning of each said track adjusting wheel at said wheel shaft two ends.
The present invention also provides a kind of road and rail double duty tractor, comprises car body, wherein, also comprises the arbitrary described guiding support device of the present invention, and the cylinder body of support cylinder is captiveed joint with said car body on the said guiding support device.
After link gear is set; Eight or outer eight mode of motion can not appear in the track adjusting wheel that is positioned at the wheel shaft two ends; The state of keeping parallelism motion always; So just greatly reduce the running resistance of vehicle in operational process, and reduce the probability that derailment occurring occurs, improved traveling security.
